BACKGROUND OF THE INVENTION 1. Field of the Invention

The present disclosure relates to an optical image capturing system, and more particularly to a compact optical image capturing system which can be applied to electronic products.

2. Description of the Related Art

In recent years, with the rise of portable electronic devices having camera functionalities, the demand for an optical image capturing system is raised gradually. The image sensing device of ordinary photographing camera is commonly selected from charge coupled device (CCD) or complementary metal-oxide semiconductor sensor (CMOS Sensor). In addition, as advanced semiconductor manufacturing technology enables the minimization of pixel size of the image sensing device, the development of the optical image capturing system directs towards the field of high pixels. Therefore, the requirement for high imaging quality is rapidly raised.

The traditional optical image capturing system of a portable electronic device comes with different designs, including a fourth-lens or a fifth-lens design. However, because of the higher pixels in portable electronic devices with camera and because of the requirement for a large aperture of an end user, e.g. functionalities of micro filming and night view, the optical image capturing system in prior arts cannot meet the advanced requirement of photography and filming.

Therefore, how to effectively increase the amount of light admitted into the optical lenses, and further improves the quality of the formed image has become quite an important issue.

SUMMARY OF THE INVENTION

The aspect of embodiment of the present disclosure directs to an optical image capturing system and an optical image capturing lens which use combination of refractive powers, convex and concave surfaces of six-piece optical lenses (the convex or concave surface in the disclosure denotes the change of geometrical shape of an object-side surface or an image-side surface of each lens element at different heights from an optical axis) and elements of insertion mechanism for positioning the lens element to increase the amount of light admitted into the optical image capturing system, and to improve imaging quality for image formation, so as to be applied to minimized electronic products.

A maximum effective half diameter position of any surface of single lens element means the vertical height between the effective half diameter (EHD) and the optical axis where the incident light of the maximum view angle of the system passes through the farthest edge of the entrance pupil on the EHD of the surface of the lens element. For example, the maximum effective half diameter position of the object-side surface of the first lens element is denoted as EHD11. The maximum effective half diameter position of the image-side of the first lens element is denoted as EHD12. The maximum effective half diameter position of the object-side surface of the second lens element is denoted as EHD21. The maximum half effective half diameter position of the image-side surface of the second lens element is denoted as EHD22. The maximum effective half diameter position of any surfaces of the remaining lens elements of the optical image capturing system can be referred as mentioned above.

The Lens Element Parameter Related to Assembly Structures of the Lens Elements

The object-side surface of each lens element of the optical system may have a bearing surface of object side depending on the requirement, and the image-side surface thereof has a bearing surface of image side. Depending on the requirement, the bearing surface of object side and the bearing surface of image side of each lens element may be respectively configured to be mutually inserted to the adjacent front lens element and the adjacent rear lens element via the contact surfaces thereof, so as to form a stacked structure (the length of the outline of the contact surface in the radial direction of the lens is denoted by BSL). The stacked structure may be designed as a single-insertion structure based on requirement, e.g. the first lens element has a first bearing surface of image side on the image-side surface thereof, and the second lens element has a second bearing surface of object side on the object-side surface thereof, such that the second bearing surface of object side contacts with the first bearing surface of image side and both of them are inserted to each other. Alternatively, the stacked structure may be designed as a double-insertion structure, e.g. a double-insertion structure is provided on the basis of the single-insertion structure. The second lens element has a second bearing surface of image side, the third lens element has a third bearing surface of object side, and the third bearing surface of object side contacts with the second bearing surface of image side such that both of them are inserted to each other.

Alternatively, the structure can be a triple-insertion structure or a full-insertion structure. An optical image capturing system with seven-piece optical lenses, for example, is provided on the basis of double-insertion structure. The third lens element has a third bearing surface of image side on the image-side surface thereof, the fourth lens element has a fourth bearing surface of object side on the object-side surface thereof, and the fourth bearing surface of object side contacts with the third bearing surface of image side such that both of them are inserted to each other. The fourth lens element has a fourth bearing surface of image side on the image-side surface thereof, the fifth lens element has a fifth bearing surface of object side on the object-side surface thereof, and the fifth bearing surface of object side contacts with the fourth bearing surface of image side such that both of them are inserted to each other. The fifth lens element has a fifth bearing surface of image side on the image-side surface thereof, the sixth lens element has a sixth bearing surface of object side on the object-side surface thereof, and the sixth bearing surface of object side contacts with the fifth bearing surface of image side such that both of them are inserted to each other, The sixth lens element has a bearing surface of image side on the image-side surface thereof, the seventh lens element has a seventh bearing surface of object side on the object-side surface thereof, and the seventh bearing surface of object side contacts with the sixth bearing surface of image side such that both of them are inserted to each other.

Take the full-insertion structure of the aforementioned optical image capturing system with seven-piece lenses for example, the extension lines of the first bearing surface of image side to the seventh bearing surface of image side are extending toward the object side or image plane according to requirement and intersect with the optical axis to form angles IAG, which are respectively represented by IAG1, IAG2, IAG3, IAG4, IAG5, IAG6, IAG7. The first bearing surface of object side to the seventh bearing surface of image side are extending to object side or image side according to requirement and have a cross angle of OAG with the optical axis, which are respectively represented by OAG1, OAG2, OAG3, OAG4, OAG5, OAG6, and OAG7.

The values of the angles IAG and OAG mentioned above should be manipulated manually. Generally, the greater the angles IAG and OAG are, the more the optical image capturing system can be minimized, but it will cause the insertion between one lens element and the other to be less secured. Conversely, if the IAG and OAG have a smaller the angle, the degree of minimization of the optical image capturing system will be smaller, but the insertion between one lens element and another is more secured.

The foregoing stacked structure can effectively prevent the tilting of the assembly of lens elements caused by the lack of precision in the inner wall of the positioning structural element during the assembling of the lens elements in the positioning structural element (e.g. the lens barrel), which will affect the quality of the captured image. Besides, when the optical image capturing system of the present invention is to be minimized, or when the pixels of image sensor in the optical image capturing system are to be minimized, the precision of assembly and bearing between one lens element and another will have high impact on the quality of image formation; whereas the aforementioned stacked structure is able to effectively ensure that the performance of each assembled and borne lens element is close to the designed values.

The length of the outline curve of any surface of a signal lens element in the maximum effective half diameter position affects the functions of the surface aberration correction and the optical path difference in each view field. The longer outline curve may lead to a better function of aberration correction, but the difficulty of the production may become inevitable. Hence, the length of the outline curve of the maximum effective half diameter position of any surface of a signal lens element (ARS) has to be controlled, and especially, the proportional relationships (ARS/TP) between the length of the outline curve of the maximum effective half diameter position of the surface (ARS) and the thickness of the lens element to which the surface belongs on the optical axis (TP) has to be controlled. For example, the length of the outline curve of the maximum effective half diameter position of the object-side surface of the first lens element is denoted as ARS11, and the thickness of the first lens element on the optical axis is TP1, and the ratio between both of them is ARS11/TP1. The length of the outline curve of the maximum effective half diameter position of the image-side surface of the first lens element is denoted as ARS12, and the ratio between ARS12 and TP1 is ARS12/TP1. The length of the outline curve of the maximum effective half diameter position of the object-side surface of the second lens element is denoted as ARS21, and the thickness of the second lens element on the optical axis is TP2, and the ratio between both of them is ARS21/TP2. The length of the outline curve of the maximum effective half diameter position of the image-side surface of the second lens element is denoted as ARS22, and the ratio between ARS22 and TP2 is ARS22/TP2. The proportional relationships between the lengths of the outline curve of the maximum effective half diameter position of any surface of the other lens elements and the thicknesses of the lens elements to which the surfaces belong on the optical axis (TP) are denoted in the similar way.

The length of outline curve of half of an entrance pupil diameter of any surface of a single lens element especially affects the functions of the surface aberration correction and the optical path difference in each shared view field. The longer outline curve may lead to a better function of aberration correction, but the difficulty of the production may become inevitable. Hence, the length of outline curve of half of an entrance pupil diameter of any surface of a single lens element has to be controlled, and especially, the proportional relationship between the length of outline curve of half of an entrance pupil diameter of any surface of a single lens element and the thickness on the optical axis has to be controlled. For example, the length of outline curve of the half of the entrance pupil diameter of the object-side surface of the first lens element is denoted as ARE11, and the thickness of the first lens element on the optical axis is TP1, and the ratio thereof is ARE11/TP1. The length of outline curve of the half of the entrance pupil diameter of the image-side surface of the first lens element is denoted as ARE12, and the thickness of the first lens element on the optical axis is TP1, and the ratio thereof is ARE12/TP1. The length of outline curve of the half of the entrance pupil diameter of the object-side surface of the first lens element is denoted as ARE21, and the thickness of the second lens element on the optical axis is TP2, and the ratio thereof is ARE21/TP2. The length of outline curve of the half of the entrance pupil diameter of the image-side surface of the second lens element is denoted as ARE22, and the thickness of the second lens element on the optical axis is TP2, and the ratio thereof is ARE22/TP2. The proportional relationship of the remaining lens elements of the optical image capturing system can be referred as mentioned above.

The height of optical system (HOS) may be reduced to achieve the minimization of the optical image capturing system when the absolute value of f1 is larger than f6 (|f1|>f6).

When |f2|+|f3|+f4|+|f5| and |f1|+|f6| are satisfied with above relations, at least one of the second through fifth lens elements may have weak positive refractive power or weak negative refractive power. The weak refractive power indicates that an absolute value of the focal length of a specific lens element is greater than 10. When at least one of the second through fifth lens elements has the weak positive refractive power, the positive refractive power of the first lens element can be shared, such that the unnecessary aberration will not appear too early. On the contrary, when at least one of the second through fifth lens elements has the weak negative refractive power, the aberration of the optical image capturing system can be corrected and fine tuned.

The sixth lens element may have negative refractive power and a concave image-side surface. Hereby, the back focal length is reduced for keeping the miniaturization, to miniaturize the lens element effectively. In addition, at least one of the object-side surface and the image-side surface of the sixth lens element may have at least one inflection point, such that the angle of incident with incoming light from an off-axis view field can be suppressed effectively and the aberration in the off-axis view field can be corrected further.

The Third Embodiment (Embodiment 3)

Please refer to FIG. 3A, FIG. 3B and FIG. 3C, FIG. 3A is a schematic view of the optical image capturing system according to the third embodiment of the present application, FIG. 3B is longitudinal spherical aberration curves, astigmatic field curves, and an optical distortion curve of the optical image capturing system in the order from left to right according to the third embodiment of the present application, and FIG. 3C is a lateral aberration diagram of tangential fan, sagittal fan, the longest operation wavelength and the shortest operation wavelength passing through an edge of the entrance pupil and incident on the image plane by 0.7 HOI according to the third embodiment of the present application. As shown in FIG. 3A, in order from an object side to an image side, the optical image capturing system includes an aperture stop 300, a first lens element 310, a second lens element 320, a third lens element 330, a fourth lens element 340, a fifth lens element 350, a sixth lens element 360, an IR-bandstop filter 380, an image plane 390, and an image sensing device 392. In the present embodiment, all of the bearing surfaces of image side and all of the bearing surfaces of object side of the lens elements are configured to extend toward the object side and intersect with the optical axis to form angles (not shown).

The first lens element 310 has positive refractive power and it is made of plastic material. The first lens element 310 has a convex object-side surface 312 and a concave image-side surface 314, and both of the object-side surface 312 and the image-side surface 314 are aspheric and have one inflection point.

The second lens element 320 has negative refractive power and it is made of glass material. The second lens element 320 has a concave object-side surface 322 and a concave image-side surface 324, and both of the object-side surface 322 and the image-side surface 324 are aspheric and have one inflection point.

The third lens element 330 has negative refractive power and it is made of plastic material. The third lens element 330 has a convex object-side surface 332 and a concave image-side surface 334, and both of the object-side surface 332 and the image-side surface 334 are aspheric and have two inflection points.

The fourth lens element 340 has positive refractive power and it is made of plastic material. The fourth lens element 340 has a convex object-side surface 342 and a concave image-side surface 344, and both of the object-side surface 342 and the image-side surface 344 are aspheric and have two inflection points.

The fifth lens element 350 has positive refractive power and it is made of plastic material. The fifth lens element 350 has a concave object-side surface 352 and a convex image-side surface 354, and both of the object-side surface 352 and the image-side surface 354 are aspheric and have one inflection point.

The sixth lens element 360 has negative refractive power and it is made of plastic material. The sixth lens element 360 has a convex object-side surface 362 and a concave image-side surface 364 and both have one inflection point. Hereby, the back focal length is reduced to miniaturize the lens element effectively. In addition, the angle of incident with incoming light from an off-axis view field can be suppressed effectively and the aberration in the off-axis view field can be corrected further.

The IR-bandstop filter 380 is made of glass material without affecting the focal length of the optical image capturing system and it is disposed between the sixth lens element 360 and the image plane 390.

Please refer to the following Table 5 and Table 6.

The detailed data of the optical image capturing system of the third embodiment is as shown in Table 5.

The Sixth Embodiment (Embodiment 6)

Please refer to FIG. 6A, FIG. 6B and FIG. 6C, FIG. 6A is a schematic view of the optical image capturing system according to the sixth Embodiment of the present application, FIG. 6B is longitudinal spherical aberration curves, astigmatic field curves, and an optical distortion curve of the optical image capturing system in the order from left to right according to the sixth Embodiment of the present application, and FIG. 6C is a lateral aberration diagram of tangential fan, sagittal fan, the longest operation wavelength and the shortest operation wavelength passing through an edge of the entrance pupil and incident on the image plane by 0.7 HOI according to the sixth embodiment of the present application. As shown in FIG. 6A, in order from an object side to an image side, the optical image capturing system includes an aperture stop 600, a first lens element 610, a second lens element 620, a third lens element 630, a fourth lens element 640, a fifth lens element 650, a sixth lens element 660, an IR-bandstop filter 680, an image plane 690, and an image sensing device 692. In the present embodiment, all of the bearing surfaces of image side and all of the bearing surfaces of object side of the lens elements are configured to extend toward the object side and intersect with the optical axis to form angles (not shown).

The first lens element 610 has positive refractive power and it is made of plastic material. The first lens element 610 has a convex object-side surface 612 and a concave image-side surface 614. The first lens element 610 and the image-side surface 614 are aspheric and both have one inflection.

The second lens element 620 has negative refractive power and it is made of plastic material. The second lens element 620 has a convex object-side surface 622 and a concave image-side surface 624, and both of the object-side surface 622 and the image-side surface 624 are aspheric and have one inflection point.

The third lens element 630 has negative refractive power and it is made of plastic material. The third lens element 630 has a concave object-side surface 632 and a concave image-side surface 634, and both of the object-side surface 632 and the image-side surface 634 are aspheric. The object-side surface 632 has three inflection points and the image-side surface 634 has two inflection points.

The fourth lens element 640 has positive refractive power and it is made of plastic material. The fourth lens element 640 has a convex object-side surface 642 and a convex image-side surface 644, and both of the object-side surface 642 and the image-side surface 644 are aspheric. The object-side surface 642 has three inflection points and the image-side surface 644 has two inflection points.

The fifth lens element 650 has positive refractive power and it is made of plastic material. The fifth lens element 650 has a concave object-side surface 652 and a convex image-side surface 654, and both of the object-side surface 652 and the image-side surface 654 are aspheric and have one inflection points.

The sixth lens element 660 has negative refractive power and it is made of plastic material. The sixth lens element 660 has a convex object-side surface 662 and a concave image-side surface 664. The object-side surface 662 and the image-side surface 664 both have one inflection point. Hereby, the back focal length is reduced to miniaturize the lens element effectively. In addition, the angle of incident with incoming light from an off-axis view field can be suppressed effectively and the aberration in the off-axis view field can be corrected further.

The IR-bandstop filter 680 is made of plastic material without affecting the focal length of the optical image capturing system and it is disposed between the sixth lens element 660 and the image plane 690.

Please refer to the following Table 11 and Table 12.

The detailed data of the optical image capturing system of the sixth Embodiment is as shown in Table 11.
